摘　　要：随着全球气温的上升和恶劣天气的频现,耐热性是水稻生产中保障产量稳定的重要特性之一。福恢676是由福建省农业科学院水稻研究所选育的优质、高配合力强恢复系,已组配了大量的杂交稻品种在生产上推广应用。为了鉴定福恢676系列杂交稻品种的耐热特性,分别以耐热品种丰两优四号和热敏感型品种盐恢559为对照,对以福恢676为父本配组的14个杂交稻品种进行室内模拟高温和室外自然高温鉴定,结果参试杂交稻品种中耐热性强的品种有2个,较强的品种有10个,一般的品种有2个,福恢676的耐热性一般。显示以福恢676为父本配组的系列杂交稻品种在生产上表现出较好的耐高温特性。With the rise of global temperature and the frequent occurrence of adverse weather,heat resistance was one of the important characteristics in ensuring stable yield in rice production.Fuhui 676 was a high-quality,high combining ability restorer line bred by Rice Research Institute of Fujian Academy of Agricultural Sciences.In order to identify the characteristics of heat resistance of the Fuhui 676 series of hybrid rice varieties,14 hybrid rice varieties hybridized with Fuhui 676 as the male parent were subjected to indoor simulated high temperature and outdoor natural high temperature identification,using the heat resistant variety Fengliangyou 4 and the heat sensitive variety Yanhui 559 as controls.Among the tested varieties,there were 2 varieties with strong heat resistance,10 varieties with stronger heat resistance,and 2 varieties with intermediate heat resistance,and restorer line Fuhui 676 showed intermediate heat resistance.The results showed that the hybrid rice varieties that were hybridized with Fuhui 676 as the male parent largely had good high-temperature resistance characteristics in production.
